Why teams look elsewhere
Four reasons people outgrow a single router
~5%
A fee on every token
A platform margin on top of provider prices is invisible at prototype volume and a real line item at production volume. Routers that bill provider rates, or let you bring your own keys, close that gap.
EU
Prompts that cannot travel
Once legal reviews the data path, a US-only proxy in front of your prompts stops being acceptable. Regional hosting, self-hosted gateways and cloud platforms keep traffic inside a perimeter you can name.
p95
Latency budgets
Voice agents and live UX spend their whole budget in the first second. A direct inference provider with no extra hop usually beats any router on speed, whatever the catalogue says.
360°
Control and visibility
Per-team budgets, spend caps, traces, caching and one invoice stop being nice-to-have the moment a second team starts calling models on the company card.
When to stay on OpenRouter: you are prototyping, you want one bill across hundreds of models, and a small fee is cheaper than running infrastructure. The planner says so too when that is the honest answer.

Short version, by situation
If you scrolled past the planner, start here.
You are prototyping and want maximum choice
Stay on OpenRouter, or use Hugging Face Inference. The per-request fee is irrelevant at small volume and the catalogue is the widest there is.
You are in production across text, voice and video
LLM API covers all four modalities behind one key with uptime monitoring and a single invoice. Novita AI is the budget alternative if you can accept lighter guarantees.
Your security team wants nothing in the data path
LiteLLM self-hosted, or Kong AI Gateway if you already run Kong. You keep provider prices with no markup and own the uptime.
Procurement has to sign off
AWS Bedrock, Azure AI Foundry or Google Vertex AI — the model spend lands on a cloud contract you already have, with residency and compliance attached.
How we compared them
Ten criteria, applied the same way to every entry, from public documentation and hands-on use.
- Model breadth and how fast new releases land
- Modality coverage: text, vision, speech, video, OCR
- Routing, retries and failover behaviour
- Pricing shape: markup, credits, invoices, commitments
- Spend controls, budgets and per-team reporting
- Data residency and regional hosting
- Self-hosting and the licence that comes with it
- White-label and reseller support
- Enterprise readiness: SLAs, SOC 2, procurement
- Migration effort from an OpenAI-compatible endpoint
What we could not measure
Latency and uptime vary by region, model and hour, so we did not publish a single speed ranking — any number we quoted would be stale by the time you read it. Support quality is reported, not tested. Where a vendor does not publish a fact, the table says so instead of guessing.

FAQ
Questions we get a lot
Still unsure after the planner? These come up in almost every migration call.
What is the best free OpenRouter alternative?
For self-hosting, LiteLLM is open source and free to run — you pay only your upstream providers. For hosted, Cloudflare AI Gateway's core features are free and sit in front of your own provider keys.
Can I switch without rewriting code?
Usually yes. Most alternatives on this page expose an OpenAI-compatible endpoint, so you change the base URL, the API key and sometimes the model-ID format. The table's pricing and routing columns flag the ones that need more than that.
Gateway or inference provider — what is the difference?
A gateway routes your requests to providers you already pay and adds control: budgets, caching, logs, failover. An inference provider runs the models itself. Plenty of teams use both, a gateway in front and two or three providers behind it.
What does BYOK mean?
Bring Your Own Key: you plug in your own OpenAI, Anthropic or Google keys, so those providers bill you directly and the router charges only for its own layer — or for nothing at all.
When should I just stay on OpenRouter?
When you are prototyping, want the widest text catalogue with no contract, and the per-request fee is smaller than the cost of running anything yourself. The planner says so too when that is the honest answer.
Is anyone paying to be on this list?
No. LLM API is our own product and is labelled as such wherever it appears. Every other entry is here on merit, scored on the same criteria from public documentation and hands-on use.
Try the one built for mixed workloads
LLM API gives you 400+ text, vision, speech and video models behind a single OpenAI-compatible key, with uptime monitoring, spend controls and one invoice. Migration is a base URL and a key.
